The articles of this special issue commemorate 25 years of the Chapter 1 compensatory education program. With the enactment of Title I of the Elementary and Secondary Education Act of 1965 the Federal government became widely and directly involved in precollegiate education. By 1991, under the Hawkins Stafford Act of 1988, the initiative, renamed Chapter 1, had made a significant mark on education. The history, achievements, and potential of Chapter 1 are discussed in the following articles: (1) "Chapter 1: An Educational Revolution. At 25, Compensatory-Education Program Strives To Reach Its Full Potential" (J. A. Miller); (2) "Studies Show Mixed Results, Spur Calls for Changes in Program" (J. A. Miller); (3) "New Provisions Forcing a Critical Look at the Quality of Services" (J. A. Miller); (4) "New Approaches to Funding, Testing, and Teaching Advocated" (D. L. Cohen); (5) "'Felton' Continues To Pose Logistical Challenges; Opponents of Services Wage New Legal Battles" (M. Walsh); and (6) "Need for Separate Handicapped Program Again Up for Discussion" (D. Viadero). Forty-three black and white photographs and six figures are included. (SLD)
